Synthesis and structural characterisation of [Pd2(μ-Br)2(PBut3)2], an example of a palladium(I)-palladium(I) dimer

The syntheses, spectroscopic characterisation and in one case (X = Br) the single-crystal structure of the novel PdI–PdI dimers [Pd2(µ-X)2(PBut3)2](X = Br or I) have been determined; preliminary results on their reactions with CO, H2, CNC6H3Me2 and C2H2 have also been obtained.

El papel de los rendimientos y la diferenciacion de productos como determinantes de la estabilidad del cartel

We study cartel stability in a differentiated quantity-setting duopoly with decreasing returns to scale. We show that a cartel may be equally stable in the presence of lower differentiation, provided that the decreasing returns parameter is higher. Furthermore, we show that, above a given discount rate, a cartel may be stable for any degree of product differentiation.
